A basemap of South Africa created by GeoSpace International found that 46,000 files being 30 TB in size nearly impossible to work with. After being compressed at 50cm GSD into a single, seamless mosaic, the resulting ECW file was 10 times smaller and still visually lossless. Their resulting savings on time and disk space was “enormous.”

If you are an AutoCAD user, performant raster imagery starts here:

  • Compress your raster imagery to ECW format with Hexagon’s GeoCompressor
  • Use Hexagon’s free ECW Plugin for AutoCAD to insert your imagery into any AutoCAD drawing


ECW for AutoCAD allows standalone compression or compression on cloud using M.App Chest cloud storage.

Serve ECW image files efficiently via ERDAS APOLLO via low bandwidth environments or through ECW for ArcGIS plugin on the ESRI server.
